Every car is very basic at the moment with many parts missing before the first test, so too early to say really. You can only really judge features built into the chassis like sidepod shape and undercut, and on that aspect the Sauber has definitely been the most interesting/impressive. McLaren look to have improved a lot of the features on their car, Ferrari and Lotus look solid, something funny is going on with the rear of the Mercedes, and Red Bull haven't given anyone a chance to have a good look at the important bits yet!

I've not really found myself drawn to one as of yet. Last year it was McLaren, for the obvious reason, although in terms of livery I definitely preferred the Lotus. This year, just in terms of the livery, nothing seems head and shoulders above the rest (in my eyes, anyway). Would've said Lotus again, but I find the red a little off-putting. Maybe Ferrari, actually. Looks better from the front, though.

The Sauber livery is probably my least favourite, and reminds me way too much of the 2010 Hispania.

The 2013 Ferrari looks sleeker than its recent predecessors and could be quick. It is also the best looking car, edging out the McLaren. Somehow, I was not that much taken with the new Sauber, mainly because of the dull livery.

The most horrendously ugly car is undoubtedly the RB9, with its lack of a modesty panel and that purple haze. But then, F1 isn't a beauty competition.

Lotus, the Red and black don't go IMO. The reds to bright or something and it's sore on the eyeballs.

Macca. More of the same. It's starting to look dated.

Ferrari again more of the same. I wish they would go back to the early'90s Red with the black wings.

Force India more of the same AGAIN. No good for a drive up the Shankill.

Sauber probably the best but a bit '10 HRT.

Red Bull. The flip paint just makes me think of all the chavvy sprayers at a training school near my old work. They used to all spray their Novas in the clown paint because it was cheap for them and supposedly the in thing for pretending they were Vin Diesel and Paul walker.

Merc, never liked the colour scheme it's just a dull grey and a really ugly green and that nose looks iffy.

I don't think so. I pulled out from Google Images, yet I might be wrong. Anyhow, didn't seem much different from STR 7, same livery, although the rear portion of the car seems very unusual, they might be better this year.

Yup, that's their 2012 car with the horrifically ugly Platypus nose. Here's their still not very pretty 2013 car with the gherkin poor Modesty Panel just unveiled:

I've already said it and seems I have no choice but to say it again: Plotus, precisely because of the platypus. Although, I agree with Johnston about the red colored parts, they don't look good. Last years color scheme was better. But the car is the best looking of all so far.

The Red Bull just looks fairy cakes. Really, really fairy cakes.The Macca is nice but its getting tiredThe Lotus has a broken colour schemeThe STR is in the same situation as the MaccaAs is the Force IndiaAnd the MercThe Ferrari has a nice subtle change with the black but I'd still like to see more going on than just red slapped on the car with a Ferrari badge.

Sauber for me, mainly due to that livery, so nice. Also F138 looks cool. Other cars (except for Lotus, but not in good way...) looks pretty much the same as last year (liveries I mean). In example, McLaren can be nice looking car overall but that livery is just so "old" that I got bored by it . But that is just my opinion.

Marussia for me even though nothing really stands out for me.Looking at these I realize how much I miss the late eighties and early nineties liveries.

Me too.

I think the downfall these days is that teams try to incorporate so many different sponsors' colours...to the extent that i don't even notice who the sponsor is anymore because I just think "pile of puke".

I'd hardly call the Caterham british racing green anymore, going on the pictures...and where are the bright yellow, green and orange liveries of yesteryear...it's all very conservative, and when it's not it's covered in big letters which are really ugly.
